CAR-COUPLING.

EPECIPICATION forming part of Letters Patent No. 318,107, dated May 19,1885. Application tiled March 11, 1885. (No model.)

To all whom it may concern.-

Be known that I, SAMUEL F. GREEN, a cilizen of the United States,residing at Salamanca, in the county of Oattaraugus and State of NewYork, have invented certain new and useful Improvements in Oar-Couplers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in that class of car-couplers inwhich the coupling is automatic or self-acting; and the object of myinvention is to produce a coupler which can be easily and safelyuncoupled without eutering between the cars, and therefore without risktolife orlimb, and which will be sim ple of construction, cheap tomanufaeture,and durable. This obj eet I attain by the construction andcombination of parts as hereinafter described and claimed.

In the accompanying drawings, Figure l isa perspective view of my devicecoupled; Fig. 2,a like view showing it uncoupled; Fig. 3, a plan view-ofthe receiving ordra-w head; Fig. at a like view of the arrow-headedcoupling link or bolt, and Fig. 5 a detail view of the operating-lever.

Similarletters refcrto similar partsthrouglr out the several views.

A represents the receiving or draw head. This head is made of springmetal, preferably in two parts, and secured together at the end lettered(t by bolt or otherwise, so as to resist the strain when the jaws B areforced apart. The jaws B are curved or flare outwardly and away fromeach other at b, so as to leave sufficient space for the arrow-headedlink or bolt 0 to readily find its way between them to force them apart.

The jaws B are notched on their contiguous faces immediately in the rearof their curved faces I), so as to form a heart-shaped recess, D, whenbrought together, as shown in Fig. 1. The link 0, as before stated, isshaped like an arrow at its head and enters between the jaws until itspoints slip past the points of the recess,when the jaws close and holdthe link securely in place. As shown, the link 0 conforms to thecurvature of the jaws B at the point b,so that it may allow of play inrounding curves without forcing the jaws apart. Immediately in the rearof the heart-shaped recess or opening D the jaws are cut away,so as toleave an oval opening,E,when brought together.

F is a lever having an oval-shaped projec tion, G, on one end whichenters the opening E of the head from beneath and fills it closely whenthe parts are in'the position shown in Fig. 1. This projection G is soarranged on the lever that a line drawn through its longest diameterwould strike an angle of about fortyfive degrees to a straight linedrawn through the lever in the direction of its length. This arrangementpermits the lever F to extend outwardly and backwardly from the headwhen the jaws are closed, so as to be easily gi aiped by the operatorwithout going between the cars. Upon turning thelever to the right, Fig.1, the projection G forces the jaws apart, which permits of thewithdrawal of the link 0, and thus uncouples the cars. The lever F restsand slides on a notched bar, H, which projects from the car to which thedraw-head A-is attached, and is held in any desired position by catchingthe notches.

Vhat I claim as new,aud desire to secure by Letters Patent, is-

A car-coupler comprising a spring-metal head, A, having the oval openingE, thejaws B, having the heartshaped opening I) and curved faces I), thelever F,having projection G, the notched bar H, and the arrow-headedlink'or bolt 0, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
